Aiiiilication filed September 17, I914. S eria1 lI o.,862,239..

T 0 all whom it may concern Be it known that We, CHARLES Ml HEE rER, COLONEL C. HEETER, and J osnr'HNY. HEETER, citizens of the United States, and residents of Butler, in the'county of Butler and State of Pennsylvania, have invented certain. new

and useful Improvements in -Methods of- Specifi'cation of Letters Patent. Pgmt'ie ntmjl Jan.2 5,1916.

with thea tesult' that the lower portion-0f passajge.- b is contractedand' closed, or substantially closed, as shown in Fig=; 3-. If not entirely'closed by the forging operation, a.

.core. or plug H may be inserted 'toprevent Making Well-Tools, of-which the following is a specification.

This invention relates. to well tools, an I particularly tools which embody a swivel,

such as a tubular or inclosed j 'ar,'-and the primary object is toprovide a durable tool of simple construction in conjunction with an economic and highly efficient method of constructing the same.

WVhile the inventi'on may be I vii-ten utilized and embodied, its adap ation, to' a water from draining into the coupling box J formed in the contracted -l ow er extremity of the tool'part. Plug "H may be of steel "and permanently held by the forging operation, or it may be formed ofwood, as may be preferred. The forging .-o,peration may also be utilized in formng the opposite wrench-hold flask. A drain-hole L may be provided for the closed lower end'of the cavity 6.

- An alternative method and embodiment of the lower element of the to0l }is illustrated swivel tool is of special importance a-s -itaffords a simple andeffect'ivemeans of as .sembling andmaintainrng -assembled the connected parts. I v In the. accompanying drawings, l igures land 2 are sectional-views of blanks from which the-swivel-connected partsof a well tool are'formed. Fig.3 is a longitudinal section of one form of acompleted tool em-' bodying the invention, andFig. t is a simi-j lar'view of a portion of a tool disclosing, a modified adaptation. Referring to Figs. 1 and .2,-A and B indicate, respectively, the billet-like steel blanks from which the swivel-connectedtool parts are formed. Part A is formed with an axial cavity a; which extends inwardly or up-' wardly from its lower end, and part Bis "formed with a through longitudinal. pas-1 sage, the larger portion 1) extending from the lower end while the upper portion is contracted as indicated at b, a shoulder G being thus formedat 'the'juncture of the passage portions. The surrounding wall D of the lower portion-of passage 6 is relatively thick-or heavy and the sameis true of Wall E which surrounds cavity a. A swivel stem F is entered in passage band at its and henceis adapted to engage shoulder After the headed stenrhas been entered 1n passage 5, with stem F extending through passage-portion b, the lower portion of part B is contracted by forging, the forged portion being the thickened wall part D portion of the tool as .in Fig.3,a1sho rt iStem section 0 is provided, in theilower, end of as indi-'.

which the coupling box J is formed. A i

'. shank 'P 'of reduced diameter projects from the upper end of stem 0 and is entered in -th.e':lower:portionof the passage in part N,

' the shank bjeing'formed with the spaced 'annu'lar enlargements'Q. These enlargements efiectimakjing parts M. and O substantially 1. integral. x

are of a sizetto enterthe passage in part M,

whereupon the thickened wall portion-ll is reduced by-forging and contractedinto the spaces between the shank enlargements Q, thereby providing a permanent joint and in- The' projecting upper portionof the, swivel stem F is formed withthe alternate annular ridges and depressions B and- B, respectively, .and the stem part of this irregular form is-adaptede to be entered in cavity a of the'upper tool part A, after which the thickenedlower wall portion of the-latter is reduced by forging and contracted into cavities R and into tight enlower extremity is provided withhead G which is larger than passage portion 6-,

gagement with enlargement It, thereby providing a secure and in eflect integral union between the parts.

From the foregoing it will be apparent that the principles "involved inthe union be-' When the invention is utilized andembodied in a swivel jar of the forms shown in Figs. 3 and 4, there is ample clearance for the necessary relative rotary movement of the connected parts, also for the longitudinal movement necessary to enable the upper tool part to strike the swivel head-confining part when jarring.

While the invention is particularly applicable to a well tool of the character described, it is not limited thereto.

We claim:

' 1. The method herein described of uniting two parts of a swivel well tool, consisting in forming one part with a through longitudinal passage of reduced diameter for a portion of its length, entering a headed swivel stem in said passage with the stem I ber.

2. The method herein described of uniting two parts of a well tool, consisting in forming one part with a through longitudinal passage which is of reduced diameter for a portion of itslength, entering a headed swivel stem in said passage with the stem extending through the reduced portion of the passage and with the head larger than the said reduced portion, and contract-v ing that portion of the passage fOrmed part through which the larger end of the pas-- sage extends and thereby inclosing the stem head.

3. The method herein described of forming a swivel well tool consisting in forming a tool part with a through cavity of reduced diameter adjacent one end, forming a stem passage open through with a head at one end and with surface irregularities adjacent its opposite end, entering the stem in the through passage with the portion thereof of irregular form extending through the reduced portion of the passage and with the stem head of larger diameter than said reduced portion, contracting the extremity of the passageformed part'through which the larger end of the passage opens and thereby confining the stem head within said larger passage portion, forming another tool part with a an end thereof and entering in said passage the portion of the stem formed with irregularities, and finally forging the passage-formed portion of the last mentioned tool part into the irregularities of the stem and thereby forming a permanent union therewith.

4. The method herein described of constructing a swivel tool, consisting in forming a tool part with a through longitudinal passage with one end of the passage contracted and with the wall of the opposite portion of the passage abnormally. thick, entering a' headed stemin the through passage with the stem extending through the tures in presence of two witnesses.
